I don’t claim to know much about ratting. But when I first started I had some rats so close, that a bayonet would’ve served well. So my expensive PCP rifles were useless for rats 10 yards and in. Enter the pp700sa which has taken hundreds of rats from 5 to 25 yards. At one particular dairy I can set up for 40 to 50 yard shots on some rats. But that’s the exception. In practice most of these pests are too close to shoot with my rifle setups. My latest rat kill was at sub 10 yards. I started with an Crosman 1377 and am rediscovering how effective low power pesting can be. Particularly at sub 25 yard distances.
